Data Representation Part 3 HW3
1. Convert each decimal number to its 9's complement (use as many digits as shown):
a) 73
b) 40512
c) 980034
d) Perform subtraction using 9's complement: 5042-671
2. Convert the following decimal numbers to the 10's complement:
a) 128
b) 4097
c) 56020
d) Perform subtraction using 10's complement: 3205-4879
3. Perform the following multiplications. Assume that all values are unsigned
numbers. (No problem with unsigned (always positive) numbers, just use the same
standard techniques as in base 10.)
a) 10112 × 01012
b) 011012 × 001112
c) 1100102 × 10112
d) 10110102 x 111012
4. Perform the following multiplications. Assume that all values are signed 2's
complement numbers.
a) 11002 01112
b) 00102 x 10102 - first multiply without sign-extending (show the wrong
result), then redo with proper sign-extension.
c) 111002 × 000112
5. Perform the following divisions. Assume that all values are unsigned numbers.
a) 1011012 ÷ 1102
b) 1000112 ÷ 1012
